Original application led January 16, 1917, Serial No. 142,677. (Patent No. 1,262,949, dated April 16, 1918.)

Divided and this application filed .Tune 8, 1917.- Serial No. 173,608.

To all whom it may concern:

Be it known that I, EDWARD M. HEYLMAN, a citizen of the United States, and a resident ofSouth Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements inA Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in plows and more particularly to such as are associated with a t'ractor and known in the art as engine gang ploWs,-this application being a division of lapplication led by me on the 16th day of January, 1917, and designated by Serial No. 142,677, now Patent No. 1,262,949, dated Apr. 16,1918. l

One object of my present invention 1s to provide simple and eiiicient means which will facilitate the'turning of the plow without removing the same from the ground.

A further object isl to so construct and arrange the .connections between the plow and the tractor that the plow will, while in the ground, properly trail when the tractor is turned or run in a curved direction, without imparting lateral strain to such connections or to the tractor.

A further object is to so connect the plow withthe tractor that a pivotal connection having a vertical axis will be afforded approximately under the rear axle of the tractor. V

A further object is to provide a draft device between the plow and tractor, embodying a horizontally'disposed turn-table disposed approximately under the rear axle of the tractor and with which the plow is pivotally connected.

A further object is to so construct a draft u device between a plow and a tractor, that both horizontal and vertical pivotal connections shall be aiforded for the plow approximately under the rear axle of the tractor.

With these and other objects in View, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims. a In the accompanying drawings, Figure 1 is a side elevation of an engine gang plow structure embodying my improvements;

Fig. 2 is a side elevation (partly in section) Fig 3 1s an end view partly in section showing the connections of the draft bail with the tractor and portions of the adjusting mechanism; Fig. 4 is a plan View, partly in section showing means for connecting the same with the'tractor and With the plow beams,4 and Fig. 5 is an enlarged detail sectional view.

l represents the rear portion of a tractor, to which the casings 2 -3 are secured for inclosing portions of the driving gearing (not shown) and for providing mountings for the axle 4 to which the rear tractor' wheels 5 are connected.

Brackets 7 and 8 are secured to the frame of the tractor forwardly of the axle and depend from said frame, said brackets being spaced apart as shown in Fig, 3 and con-I nected by a brace bar 9. Braces 10 are secured to the lower ends of the brackets and to the tractor forwardly of said brackets, as shown in Fig. 1.

The forward end of a draft bail 1l is pivotally connected with the depending brackets 7, 8 and projects therefrom rearwardly under the rear axle of the tractor to receive the beam members 12, 12 of a plow gang 13,-the connection of said beams with the bail being effected through the medium of a turntable 14 carried by the bail approximately under the rear axle of the tractor.

In effecting the pivotal connection of the forward end the bail 11 with the brackets 7, 8, the bail is provided with lateral pintles 15, 16 to enter openings 17, 18 in the lower portions of the brackets 7, 8. The opening 17 in which the pintle 15 has its bearing at the lower end of the bracket 7 may be circular and of such size that the pintle 15 shall fit loosely therein, while the opening 18 into which the pintle 16 enters, is made in the form of an elongated slot, and the lower portion of the bracket 8 is curved somewhat so that the slot therein shall be segmental in form. From this construction, it will be f apparent that the bail may be tilted in such shaft 22 is mounted in the brackets i9 and 2G and provided with a rearwardly projecting arm 23 connected, by :means ot a rod 2d, with the tf-shaped rear end 26a of the draft bail ll. il hand lever 26 is secured to the shaft 22 and provided with a suitable detent to engage the toothed segment 2l. By operating the lever 26, the draft bail may be moved vertically and the plow gang thus adjusted for depth of plowing.

A bell cranlr lever 27 is pivotally mounted on the bracket 8 and the lower arm oi this bell crank is connected with the vertically movable pintle 16 at the forward right hand corner oi the bail by means oi a rod 28. ln effecting such connection, a bolt 29 is mounted in the tubularpintl lo (Fig. a) and pro vided at-its outer end with an eye to receive a similar eye at the lower end ol the rod 28. 'lhe upper arm of the bell cranlr 2? is connected, by means of a rod 30 with an arno. 3l projecting vupwardly from the shalt 22. ln ei'ilecting the connection between `the rod 30 and arm 3l, an interiorly threaded sleeve 32 is pivotally mounted on the arm 3l tor the passage ot the threadedy portion 83 or" said rod, thus providing an adjustable con? nection between the rod and arm. With such construction, the operation of the lever .26 to adjust the plows for depth of plowing, will also cause one sideof the dralt bail to be raised and in this manner the plows may be leveled and adjusted for depth ora plowing, simultaneously with the use oi a single operating lever. v

The drait bail ll is provided intermediate of its ends with a circular portion 3i having an annular groove in which the turn- Y table ld is mounted. rlhe turntable may be conveniently made in two semi-circular sec= tions 36-36, provided at their ends with lugs 3l' through which securing bolts 3d are passed. The respective sections oi the turntable are provided intermediate ot their ends with interiorly threaded bosses 39 and the inner ends of these bosses enter grooves d0 formedy in the periphery of the circular mounting Bel to serve as liinit stops for the turntable. lleaded studs Lll are screwed into the bosses 39 and to the projecting ends ci these studs, the forward ends ci? the beam members l2 ot theplow gang are pivotally connected.

lt will be observed that with the construction and arrangement'ot parte as hereinbefore described, the plow is connected with a pivoted draft bail in such manner that two pivotal connections of said plow with the bail are effected under the rear axle or the tractor, and that said pivotal connections are disposed at right angles to each other, the turntable adording a pivotal connection having a vertical axis permitting lateral movement oi the plow relatively to the trac il tor, and the attachment or the beain mena incesti details 0:? construction ci roy invention without departing from the spirit thereof or limiting its scope, and hence l do not wish to restrict niyselt to the precise details herein set forth.

Having Fully described my invention what l claim as new and desire to secure by Letters-Patent, is

l. An engine plow structure, comprising a tractor, a drait device connected, with the tractor, and a plow having two pivotal oonnections with the draft device, said pivotal connections being disposed at right angles to each other and located approximately under the rear axle oi the tractor.

2. ln engine gang plow structure coinprising a tractor, a draftk bail connected therewith, a horizontal member supported by the drait bail and adapted to turn, said horizontal member being disposed between the connection of the forward portion ot the bail with the tractor and the rear portion of said bail, and a plow having pivotal connection with said horizontal meinber at right angles to the axis ofthe latter.

3. .an engine gang plow structure coinprising a tractor, a draft bail connected therewith, a turntable mounted on said bail, said turntable'being disposed between the connection of the forward portion of the bail with the tractor and the rear portion ci said bail, and a plow having pivotal con` nection with the turntable at diametrically opposite points thereon.

i d. lin engine low structure, comprising a tractor, a dra t bail connected with said tractor ml'orwardly oi" its rear axle, and a plow having vertical and horizontal pivotal connection with said draft bail approxiinately under said rear aule.

5. An engine plow structure, comprising a tractor, a droit bail connected with the tractor forwardly of' its rear aXle, a horizontally disposed turntable carried by said bail approximately under the rear aule oil' the tractonand a plow pivotally connected with said turntable.

li. ln an engine plow structure, the conibination with a tractor, of .a droit bail connected therewith, said draft bail having a circular portion between its ends, an annular turntable mounted on said circular portion ont the draft bail, a plow pivotally connected with said turntable, and means for limiting the turning movement of said turntable.

7. In anengine plow structure, the combination with a tractor, of a draft bail con- 5 nected therewith, a plow, means providing two pivotal connections at right angles to each other between the plow and the draft bail and approximately under the rear axle of the tractor, and supporting means connecting the rear and of the draft bail with 1o the tractor.
